Looks original to me I am curious which movement is inside 2522 P or the 133.8 ? 1960/61 ??

 

Bumper was made until 1958, I suppose your watch is 1960. The only way to be sure is open the watch



At that time they didn’t use to indicate the caliber

 

With a bit of luck @LouS might be able to tell.


Mine in Rose Gold

 

Thanks I will go to a watch repairer to open it I hope it’s a 133.8 I know someone
who has a Zenith Captain from early 61 with a 133.8 movement there was probably an overlap !

 

Of course, production ended in 58 but they used it surely until 60 and maybe more

 

There is another way. I’ll give you a hint—it has to do with the term “bumper.”

 

Yes I know the difference between a rotor and a bumper when you shake the watch you can hear something the spring ???

 

The good Old give it a bit of a shake and see if it bumps

 

Yes it bumps thanks for the info a 133.8 then I am happy

 

There was overlap because they had unused movements. Zenith didn’t assemble watches until there was an order to fill. If you want to know exactly when it was assembled, get an extract for €60

 

do you have an extract for yours? It’s stunning

 

No extract.

There is some nice ones owned by members here.

I would guess 1957-58 by the serial but you never know with them

 

I felt the bump

 

Hi
I’m new to this forum and perhaps a silly question. But isn’t the bumper movement with calendar a caliber 71?

 

yes
